The current treatment modes of solid wastes include modes of landfill, incineration, pyrolysis, cooking disinfection and the like; wherein, the landfill or incineration disposal causes pollution to the atmosphere and the underground water and can also generate carcinogenic substances; other treatments, such as pyrolysis and cooking, are difficult to destroy the solid matter and difficult to recycle. In addition, the pyrolysis generates carbon dioxide, dioxin and other harsh gases, and the emission of these gases, in addition to the odor, should be improved under the present severe environmental damage conditions such as suspended particles and global warming.
In addition, the waste is reprocessed to prepare a fire coal means, and the fire coal can generate heat in a weathering process, so that the control of moisture can be enhanced in the coal storage process, but a plurality of activators used for controlling addition lose catalytic action due to overhigh moisture content, and the main reason for causing the pollution reduction and emission reduction of a combustion furnace is also caused.
Therefore, there is a need to provide a method for improving the efficiency of waste recycling, so as to solve the problems in the prior art.

a waste collection step 10, which is to collect waste 11 such as domestic garbage, domestic kitchen waste, poultry excrement, animal carcasses (such as pigs, birds and the like died of diseases), infectious medical waste, organic sludge, waste plastics and the like.
A high-temperature high-pressure liquefaction hydrolysis treatment step 20, in which the waste 11 collected in the waste collection step 10 is put into a device tank 21 (shown in fig. 2), a high-temperature high-pressure environment simulating the principle of crude oil and coal generated in nature is created in the device tank 21, water is heated to a temperature above the boiling point and below the critical point, and the pressure is controlled to keep the water in a liquid state (also called subcritical water), the temperature of the water solution in the device tank 21 is 200-230 ℃, the pressure is 2-3 MPa (see fig. 3), and under the condition, the water is a polar compound and can liquefy and hydrolyze the solute from low to high according to the polarity; under the condition of controlling both temperature and pressure, the waste 11 can be hydrolyzed, so that the product obtained by hydrolyzing the dissolved organic matters is the liquid regenerated Fuel (RDF-6) 22. It should be noted that the high-temperature high-pressure liquefaction and hydrolysis step 20 mainly controls the dielectric constant of water by adjusting the temperature and pressure, and thus has environmental protection indexes under the high-temperature high-pressure treatment technique without using acid or alkali. In addition, compared with other waste treatment processes, the hydrolysis time of the high-temperature high-pressure liquefaction hydrolysis treatment step 20 is short, so that the method has the advantage of optimizing the productivity.
And a regeneration fuel drying step 30, in which the liquid regeneration fuel (RDF-6)22 obtained in the high-temperature high-pressure liquefaction hydrolysis treatment step 20 is subjected to a drying procedure, and an activating agent is added in a spraying manner when the water content of the liquid regeneration fuel 22 is 20% -5%, so that a solid regeneration fuel (RDF-5)31 is obtained. The activator comprises at least titanium dioxide (TiO)2) Zirconium oxide (ZrO)2) Niobium pentoxide (Nb)2O5) The particle size of the oxidant and activator components is between 10nm and 100nm, so that a larger contact area is formed when the oxidant and activator components act on the liquid regeneration fuel (RDF-6)22, each crystal grain is of a single magnetic structure and presents a super paramagnetic state, and therefore, the generated nano magnetic property is strong, the generated nano magnetic property has high adsorption force, and the nano magnetic property is not easy to evaporate along with the moisture of the liquid regeneration fuel (RDF-6)22 in the using process.
By the above method, the waste collection step 10, the high-temperature high-pressure liquefaction and hydrolysis treatment step 20 and the regenerated fuel drying step 30 can obtain the regenerated fuel product, and the method and the product thereof of the present invention have the following advantages:

2. The time of the high-temperature high-pressure liquefaction hydrolysis treatment step is short, and each batch of the high-temperature high-pressure liquefaction hydrolysis treatment step is generally about 2-2.5 hours, so that the method has the advantage of optimizing the productivity.
3. When the solid state renewable fuel (RDF-5)31 is provided for a boiler to use, the solid state renewable fuel can supply heat, gas and power, reduce air pollution and the generation amount of fly ash and bottom slag, and the generated fly ash and bottom slag can be reused in the building material industry or concrete factories.
4. When the solid regenerated fuel (RDF-5)31 is used, the adsorption of oxygen can be increased, so that the carbon particles are fully combusted, and strong far infrared radiation heat can be generated during combustion, thereby increasing the combustion temperature and reducing the fuel consumption.
5. The activating agent added in the step 30 of drying the regenerated fuel has excellent hydrophilicity, no fear of moisture, good temperature resistance and no special requirement for storage environment.
